  • IE and Google Chrome timeout on an IIS6 hosted SSL page that Firefox handles well.

    - by Thomas
    Ok, here's the scenario: Up until a few weeks ago, none of us noticed anything wrong with the corporate website. People were using it without complaint. Then, a client complained that a specific page on the site was timing out for him, and only when he committed a POST action on a form filled with data. I checked it out, and it timed out for me, too. But, it only timed out in Google Chrome and IE, not in Firefox. Additionally, the same page, on the same server, but served from a different domain name (one not under the protection of SSL, either) does not time out under any browser. To clarify: https://www.mysite.com/changes.php times out on POST, but the same with http works fine. That distinction (SSL vs. Non-SSL) seems to be important, as nothing else has changed. Our certificate is valid, and Firefox detects no errors thrown by the page. I've looked at the Request and Response headers from the page, and they all follow the correct formats. Then, after wandering through the site, I noticed a few other things. Both IE and Chrome will frequently time out on any page that is PHP-based. They never time out on static images or html files. I've looked at the site from a variety of different servers, my home and work workstations, and my netbook. Because of that, I've discounted a viral infection, as I highly doubt a virus is going to hit every one of the machines to which I have access in exactly the same manner. My setup is: Server: Win2k3, II6, PHP 5.2.9-1. Clients: IE7, IE8, Chrome (regular and dev channel): Frequent timeouts on PHP pages. Firefox 2, Firefox 3: No timeouts. Firebug shows no errors or even lengthy periods serving the pages. I've spent 2 days searching for any tech knowledge that I can find, and my search parameters are all too general. Everyone has problems loading SSL pages in IE and Chrome for a wide variety of reasons. The infrequent nature of the timeouts and the fact that there are no errors being reported anywhere is starting to drive me insane. Does anyone have any insight on a problem like this?

  • Are FC and SAS DAS devices standard enough?

    - by user222182
    Before I ask my questions, here is some background info that may or may not be useful: For the first time I find myself needing a DAS solution. My priority is data through-put in a single direction. I can write large blocks, and I don't need to read at the same time. The server (the data producing device) is not really a typical server, its a very powerful single board computer. As such I have limited options when it comes to the add-in cards I can install since it must use the fairly uncommon interface, XMC. Currently I believe I am limited PCIex8 gen 1 which means that the likely bottle neck for me will be this 16gbps connection. XMC Boards I have found so far offer the following connections: a) Dual 10GBE ethernet controller, total throughput 20gbps b) Dual Quad SAS 2.0 Connectors (SFF-8XXX) HBA (no raid), total throughput 48 gbps c) Dual FC 8gb HBA (no raid), total throughput 16gbps My questions for you guys are: 1) Are SAS and/or FC, and by extension their HBAs, standard enough that I could purchase a Dell or Aberdeen storage server with a raid controller that has external SAS or FC ports and expect that I can connect it to my SAS or FC HBA, be presented with a single volume (if I so configured the storage server), all without having to check for HBA compatibility? 2) On a device like a Dell PowerVault (either DAS or NAS) is there an OS on it to concern myself with, or is it meant to be remotely managed? Is there a local interface in case I cant remotely manage it (i.e. if my single board computer uses an OS not supported by Dell OpenManage). Would this be true of nearly any device which calls itself a DAS? 3) If I purchase some sort of Supermicro storage chassis, installed a raid controller with external connections, is there a nice lightweight OS I can run just for management of the controller? Would I even need an OS since the raid card would be configured pre-boot anyway? 4) It is much easier to buy XMC based 10gigabit ethernet cards (generally dual port). In what ways would I be getting into trouble by using iSCSI as a DAS are direct cabling with SFP+ cables? Thanks in advance

  • Using curl -s in *nix command line not working for some reason

    - by JM4
    I am trying to install composer (though to be honest I really have no idea how it fully works and documentation seems to be quite poor) on my MediaTemple DV machine. I am using their [instructions][1] Trying to install globally using: $ curl -s https://getcomposer.org/installer | php My command line (again using putty and logged into my server as root) thinks for a second, then sets up for next prompt. I run a simple ls -l to check for the file it should have downloaded with no luck. Any idea what could be causing the issue? I have tested and do in fact have curl installed. UPDATE 1 Based on the first answer, the verbose response is: > $ curl -vs https://getcomposer.org/installer | php > * About to connect() to getcomposer.org port 443 > * Trying 37.59.4.156... connected > * Connected to getcomposer.org (37.59.4.156) port 443 > * successfully set certificate verify locations: > * CAfile: /etc/pki/tls/certs/ca-bundle.crt CApath: none > * SSLv2, Client hello (1): SSLv3, TLS handshake, Server hello (2): SSLv3, TLS handshake, CERT (11): SSLv3, TLS handshake, Server key > exchange (12): SSLv3, TLS handshake, Server finished (14): SSLv3, TLS > handshake, Client key exchange (16): SSLv3, TLS change cipher, Client > hello (1): SSLv3, TLS handshake, Finished (20): SSLv3, TLS change > cipher, Client hello (1): SSLv3, TLS handshake, Finished (20): SSL > connection using DHE-RSA-AES256-SHA > * Server certificate: > * subject: /C=CH/CN=dl.packagist.org/[email protected] > * start date: 2012-07-07 23:25:35 GMT > * expire date: 2013-07-10 02:55:12 GMT > * SSL: certificate subject name 'dl.packagist.org' does not match target host name 'getcomposer.org' > * Closing connection #0 > * SSLv3, TLS alert, Client hello (1): > > > [1]: http://getcomposer.org/doc/00-intro.md

  • Authenticate by libpam-mysql and libnss-mysql (CentOS)

    - by Chris
    I'm trying to get MySQL to function as a backend for authenticating users on CentOS 6.3. So far I have successfully installed and configured libnss-mysql. I can test this by doing: # groups testuser testuser : sftp Testuser is a member of the sftp group in fact, all MySQL based useraccounts will be hardcoded to it. The sftp group is chrooted and forced to use internal-sftp so they cannot do anything but access their home directory. Then I configured pam-mysql and PAM to allow mysql logins. This also works.. When SELinux is not enforcing. When I do setenforce 1 users can no longer login. Error: Permission denied, please try again. This is my pam_mysql.conf file: users.host=localhost users.db_user=nss-pam-user users.db_passwd=*********** users.database=sftpusers users.table=users users.user_column=username users.password_column=password users.password_crypt=6 verbose=1 My /etc/pam.d/sshd: #%PAM-1.0 auth sufficient pam_sepermit.so auth include password-auth auth required pam_mysql.so config_file=/etc/pam_mysql.conf account sufficient pam_nologin.so account include password-auth account required pam_mysql.so config_file=/etc/pam_mysql.conf password include password-auth # pam_selinux.so close should be the first session rule session required pam_selinux.so close session required pam_loginuid.so # pam_selinux.so open should only be followed by sessions to be executed in the user context session required pam_selinux.so open env_params session optional pam_keyinit.so force revoke session include password-auth And to be complete the contents of some log files.. /var/logs/secure Nov 20 14:52:20 hostname unix_chkpwd[4891]: check pass; user unknown Nov 20 14:52:20 hostname unix_chkpwd[4891]: password check failed for user (testuser) Nov 20 14:52:20 hostname sshd[4880]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.10.107 user=testuser Nov 20 14:52:22 sftpusers sshd[4880]: Failed password for testuser from 192.168.10.107 port 51849 ssh2 /var/logs/audit/audit.log type=USER_AUTH msg=audit(1353420107.070:812): user pid=5285 uid=0 auid=500 ses=24 subj=unconfined_u:system_r:sshd_t:s0-s0:c0.c1023 msg='op=pubkey acct="testuser" exe="/usr/sbin/sshd" hostname=? addr=192.168.10.107 terminal=ssh res=failed' type=USER_AUTH msg=audit(1353420112.312:813): user pid=5285 uid=0 auid=500 ses=24 subj=unconfined_u:system_r:sshd_t:s0-s0:c0.c1023 msg='op=PAM:authentication acct="testuser" exe="/usr/sbin/sshd" hostname=192.168.10.107 addr=192.168.10.107 terminal=ssh res=failed' type=USER_AUTH msg=audit(1353420112.456:814): user pid=5285 uid=0 auid=500 ses=24 subj=unconfined_u:system_r:sshd_t:s0-s0:c0.c1023 msg='op=password acct="testuser" exe="/usr/sbin/sshd" hostname=? addr=192.168.10.107 terminal=ssh res=failed' I tried to let audit2why explain the problem but it remains silent even though there are some errors. Does anyone see the problem? Thanks! EDIT: Turns out it's almost working with setenforce 0 I can mkdir foobar but if I do a single ls I get an error: Received message too long 16777216

  • Is it reasonable that a random disk seek & read costs ~16ms?

    - by fzhang
    I am frustrated about the latency of random reading from a non-ssd disk. Based on results from following test program, it speeds ~16 ms for a random read of just 512 bytes without help of os cache. I tried changing 512 to larger values, such as 25k, and the latency did not increase as much. I guess it is because the disk seek dominates the time. I understand that random reading is inherently slow, but just want to be sure that ~16ms is reasonable, even for non-ssd disk. #include <sys/stat.h> #include <sys/time.h> #include <sys/types.h> #include <sys/unistd.h> #include <fcntl.h> #include <limits.h> #include <stdio.h> #include <string.h> int main(int argc, char** argv) { int fd = open(argv[1], O_RDONLY); if (fd < 0) { fprintf(stderr, "Failed open %s\n", argv[1]); return -1; } const size_t count = 512; const off_t offset = 25990611 / 2; char buffer[count] = { '\0' }; struct timeval start_time; gettimeofday(&start_time, NULL); off_t ret = lseek(fd, offset, SEEK_SET); if (ret != offset) { perror("lseek error"); close(fd); return -1; } ret = read(fd, buffer, count); if (ret != count) { fprintf(stderr, "Failed reading all: %ld\n", ret); close(fd); return -1; } struct timeval end_time; gettimeofday(&end_time, NULL); printf("tv_sec: %ld, tv_usec: %ld\n", end_time.tv_sec - start_time.tv_sec, end_time.tv_usec - start_time.tv_usec); close(fd); return 0; }

  • HAProxy + Percona XtraDB Cluster

    - by rottmanj
    I am attempting to setup HAproxy in conjunction with Percona XtraDB Cluster on a series of 3 EC2 instances. I have found a few tutorials online dealing with this specific issue, but I am a bit stuck. Both the Percona servers and the HAproxy servers are running ubuntu 12.04. The HAProxy version is 1.4.18, When I start HAProxy I get the following error: Server pxc-back/db01 is DOWN, reason: Socket error, check duration: 2ms. I am not really sure what the issue could be. I have verified the following: EC2 security groups ports are open Poured over my config files looking for issues. I currently do not see any.

  • Intermittent Disconnection of Client Computers from Domain Server

    - by dilip nagle
    The Background: I have Windows 2008 server Enterprise Version with 25 user cal licences. It has a domain and all users and a network shared HP printer in it. The Server has two network cards and both these cards as well as all client machines are on IP addressing scheme of 192.168.1.* with subnetmask 255.255.255.0. Of the two network cards viz. 192.168.1.231 and 192.168.1.233, only 192.168.1.231 is registered with DNS. In 192.168.1.233(i.e. 2nd network card) has default getway as 192.168.1.231 and dns address as 192.168.1.231. The Server has three hard disks with capacities as 500gb, 500gb and 1TB and are partitioned as (C,D,E), (F,G) and (K) with partition K having all user data into various Shared Folders. Each of these folders(On Partition K), are mapped onto each user's computer as per the right of access given to them. The Problem: The Server was installed about 6 months ago and till date not even once, the Server has Hung or has given any problem. All the Clients computers are able to run the web based software from their computers via ip address, e.g. http://192.168.1.231/webERP/default.aspx. However, occassionally, when any client computer tries to browse network mappings, it hangs. Again, there is no fixed pattern. This may happen after running smoothly for say 3 days. On each Client's machine, the network settings are as follows: IP Address: 192.168.1.* where * is 1,2,3 .... Sunnetmask: 255.255.255.0 defauly getway: 192.168.1.231 Which is a server card and DNS address. preferred DNS Server: 192.168.1.231 In Advanced Tab under Wins: LMHostLookup is Unticked and default is radio buttoned. Ideally, I would have loved to have Disabled NETBIOS over TCP/IP but some network printers do not get accessed if this option is enabled(ie. Radio Buttoned). Bacause Disabling Netbios will drastically reduce traffic of NETBIOS broadcasting to all the computers on the net to do naming resolution. On Server, I have WINs Running which I have Scavanged Records, verified Database Integrity etc, removed Tombstoned Records etc. The Critical Errors shown only once a day when the server is statred are 4224(WINS) and 12923 - Server Licencing failed to Update DNS Record. I fail to understand as why do client machines HANG when they try to browse mapped network shared folders on K Drive. Kindly Advice

Question: How can I exclude the child processes and only get the parent process (please note however that the processes I want do also have a parent (e.g. bash) that I'm uninterested with)? Using a regexp with grep on how much indentation there is in the ascii tree feels dirty. Is there a better way? Example: The desired output would be something like this. stpe 4222 0.0 0.2 64524 11668 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 5012 0.0 0.2 64512 11656 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py This would be easily parseable to be able to automatically find the PIDs in a script that does the HUPing which is the goal.

  • Windows Setup could not configure Windows to run on this computer's hardware

    - by Hello71
    The whole installation goes smoothly up to the point of "Completing installation ...". The monitor changes resolution, after which a standard dialog box pops up saying Windows Setup could not configure Windows to run on this computer's hardware Then, in a few seconds, the whole machine powers down. Trying to restart produces the message: STOP: c000021a {Fatal System Error} 0x00000000 (0xc0000001 0x00100448) OR it boots into Setup and comes up with the message: Windows Setup encountered an unexpected error... (This is not the actual error, just paraphrasing) I tried using the OEM restore instead of a regular install, but it fails with the same error. (Even though it worked before...) General specs: HP Pavilion Elite e9262f Intel Core i5-750 Processor ATI Radeon HD 4650 Hitachi HDT721010SLA360 ATA Device 6GB DDR3 RAM SuperMulti DVD Burner with LightScribe Some built-in Wi-Fi module http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01916917 I've tried disconnecting the wireless card and disabling the built-in Ethernet and Firewire via the BIOS, and replacing the wireless keyboard and mouse with wired USB ones. Didn't work. I've also tried changing the SATA controller settings in the BIOS to RAID, AHCI, and IDE, reinstalling each time I changed. Still not working. I think the reason why it is showing the Fatal System Error is because it didn't finish installing before it errored out and shut down, so the system is left in an inconsistent state. I've tried 3 different copies (including the OEM restore) of Windows 7 now, and they're all failing at the same point, with the same error message. I've tried to install Windows 7 maybe 10 times already, with the exact same error message at the exact same location. Hm... Interestingly, the 32-bit version of Windows 7 works, but the 64-bit version doesn't. Perhaps it was a badly burned disk? Reburning the 64-bit version still comes up with the same error. Here's a picture of the side of the case that clearly says it came with Windows 7 64-bit, along with the model number and CPU. sudo fdisk -l: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0009896f Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 7 HPFS/NTFS /dev/sda2 14 94119 755906445 7 HPFS/NTFS /dev/sda3 119922 121602 13492224 7 HPFS/NTFS /dev/sda4 94120 119922 207257740+ 5 Extended /dev/sda5 119527 119922 3170769 82 Linux swap / Solaris /dev/sda6 107174 119526 99225441 83 Linux /dev/sda7 94120 107173 104856192 7 HPFS/NTFS Partition table entries are not in disk order

  • Splunk is fantastically expensive: What are the alternatives? [closed]

    - by samsmith
    Possible Duplicate: Alternatives to Splunk? This has been discussed, but it has been several months, so it may be time to revisit it: Earlier discussion RE Splunk alternatives For the record, Splunk rocks. But the pricing is simply beyond what we can consider (When I spoke with Splunk today, the cost for a system to index 5gb/day of data is over $30,000.) That is more than we spend on SQL Server (by a large multiple), more than we spend on a rack of servers (by a multiple), etc. etc. The splunk sales team is correct (that for $30K we get more value and functionality than if we spend the same building our own system), but it doesn't matter. The splunk cost is simply too high (by a multiple). Soooooo, we are looking around! Is anyone out there building a splunk like system? Our basic need: Able to listen for syslog messages on multiple udp ports Able to index the incoming data in an async way Some kind of search engine Some kind of UI An API to the search engine (to embed in our console) We currently need to index 3-5gb/day, but need to be able to scale to 10gb/day or more. We do not need a lot of history (30 days is fine). We use Windows 2008 and 2003 servers. Thanks for your thoughts! UPDATE: We spent two weeks researching commercial and open source options. Our conclusion: Write our own (we are a software company... we know how to write things). We built a great system built on mongodb and .NET that gives us the functions we needed from MongoDB in about one engineering week. We have now completed our implementation. We use two Mongodb servers (master and slave), and are able to log and index any amount of log data (5gb/day, 15gb/day, etc), limited only by disk space. OBSERVATIONS: This space needs a solid solution that is $1000-3000 flat rate. The licensing models used by the commercial firms are based on a "milk the data center ops guys" models. That is their right (of course!), but it leaves a HUGE space open for someone to come in underneath them. My guess is that in another year or two there will be a good open source solution that will be really usable. Thank you all for your input (even if it was self promotion).

  • "Hostile" network in the company - please comment on a security setup

    - by TomTom
    I have a little specific problem here that I want (need) to solve in a satisfactory way. My company has multiple (IPv4) networks that are controlled by our router sitting in the middle. Typical smaller shop setup. There is now one additional network that has an IP Range OUTSIDE of our control, connected to the internet with another router OUTSIDE of our control. Call it a project network that is part of another companies network and combined via VPN they set up. This means: They control the router that is used for this network and They can reconfigure things so that they can access the machines in this network. The network is physically split on our end through some VLAN capable switches as it covers three locations. At one end there is the router the other company controls. I Need / want to give the machines used in this network access to my company network. In fact, it may be good to make them part of my active directory domain. The people working on those machines are part of my company. BUT - I need to do so without compromising the security of my company network from outside influence. Any sort of router integration using the externally controlled router is out by this idea So, my idea is this: We accept the IPv4 address space and network topology in this network is not under our control. We seek alternatives to integrate those machines into our company network. The 2 concepts I came up with are: Use some sort of VPN - have the machines log into VPN. Thanks to them using modern windows, this could be transparent DirectAccess. This essentially treats the other IP space not different than any restaurant network a laptop of the company goes in. Alternatively - establish IPv6 routing to this ethernet segment. But - and this is a trick - block all IPv6 packets in the switch before they hit the third party controlled router, so that even IF they turn on IPv6 on that thing (not used now, but they could do it) they would get not a single packet. The switch can nicely do that by pulling all IPv6 traffic coming to that port into a separate VLAN (based on ethernet protocol type). Anyone sees a problem with using he switch to isolate the outer from IPv6? Any security hole? It is sad we have to treat this network as hostile - would be a lot easier - but the support personnel there is of "known dubious quality" and the legal side is clear - we can not fulfill our obligations when we integrate them into our company while they are under a jurisdiction we don't have a say in.

  • How to configure Transparent IP Address Sharing (TAS) on a Mediatrix 4102 with DGW 2.0 firmware?

    - by Pascal Bourque
    I am making the switch to VoIP. I chose voip.ms as my service provider and Mediatrix 4102 as my ATA. One reason why I chose the Mediatrix over other popular consumer ATAs is that it's supposed to be easy to place it in front of the router, so it can give priority to its own upstream traffic over the home network's upstream traffic. This is supposed to work transparently, with the ATA and router sharing the same public IP address (the one obtained from the modem). They call this feaure Transparent IP Address Sharing, or TAS. Their promotional brochure describes it like this: The Mediatrix 4102 also uses its innovative TAS (Transparent IP Address Sharing) technology and an embedded PPPoE client to allow the PC (or router) connected to the second Ethernet port to have the same public IP address, eliminating the need for private IP addresses or address translations. I am interested by this feature because my router, an Apple Time Capsule, doesn't support QoS and cannot give priority to the voice packets if the ATA is behind the router. However, after hours of searching the web, reading the documentation, and good ol' trial and error, I haven't been able to configure the Mediatrix to run in this mode. Then I found a version of the manual that looks like it was for a previous version of the firmware (SIP), where there is an entire section dedicated to configuring TAS (starting at page 209). But my Mediatrix comes with the DGW 2.0 firmware, whose documentation does not mention TAS at all. So I tried to follow the TAS setup instructions from the SIP documentation and apply them to my DGW firmware, using the Variable Mapping Between SIP v5.0 and DGW v2.0 document as a reference, but no success. Some required SIP variables don't have an equivalent in DGW. So it looks like the DGW firmware does not support TAS at all, or if it does they are not doing anything to help us set it up. So right now, the Mediatrix is behind the router and VoIP works perfectly except when my upstream bandwidth is saturated. My questions are: Is downgrading to SIP firmware the only way to have my Mediatrix 4102 run in TAS mode? If not, anybody knows how to setup TAS on the DGW firmware? Is TAS mode the only way to give priority to the voice packets if I want to keep my current router (Apple Time Capsule)? Thanks!

  • networking tunnel adapter connections?

    - by Karthik Balaguru
    I understand that Tunnel Adapter LAN is for encapsulating IPv6 packets with an IPv4 header so that they can be sent across an IPv4 network. Few queries popped up in my mind based on this :- If i do 'ipconfig', Apart from ethernet adapter LAN details, I get a series of statments as below - Tunnel adapter Local Area Connection* 6 Tunnel adapter Local Area Connection* 7 Tunnel adapter Local Area Connection* 12 Tunnel adapter Local Area Connection* 13 Tunnel adapter Local Area Connection* 14 Tunnel adapter Local Area Connection* 15 Tunnel adapter Local Area Connection* 16 Except for the *16, all the other Tunnel Adapter Local Area Connections show Media Disconnected. Why is the numbering for the Tunnel adapter LAN not sequential? It is like 6, 7, 12, 13, 14, 15, 16. A strange numbering scheme! I tried to figure it out by thinking of some arithmetic series. But, it does not seem to fit in. There is a huge gap between 7 and 12. Any ideas? What is the need for so many Tunnel Adapter LAN connections? Can you tell me a scenario that requires all of those ? I did ipconfig /all to get more information. From the listing, I understand that: 16, 15, 14, 12 are Microsoft 6to4 Adapters 13, 6 are isatap Adapters 7 is Teredo Tunneling Pseudo-interface I understand that the above are for automatic tunneling so that the tunnel endpoints are determined automatically by the routing infrastructure. 6to4 is recommended by RFC3056 for automatic tunneling that uses protocol 41 for encapsulation. It is typically used when an end-user wants to connect to the IPv6 Internet using their existing IPv4 connection. Teredo is an automatic tunneling technique that uses UDP encapsulation across multiple NATs. That is, It is to grant IPv6 connectivity to nodes that are located behind IPv6-unaware NAT devices ISATAP treats the IPv4 network as a virtual IPv6 local link, with mappings from each IPv4 address to a link-local IPv6 address. That is to transmit IPv6 packets between dual-stack nodes on top of an IPv4 network. That is, to put in simple words, ISATAP is an intra-site mechanism, while the 6to4 and Teredo are for inter-site tunnelling mechanisms. It seems that Teredo should alone enabled by default in Vista, But my system does not show it to be enabled by default. Interestingly, it shows a 6to4 tunnel adapter (Tunnel adapter LAN connection 16) to be enabled by default? Any specific reasons for it? If i do ipconfig /all, why is only one Teredo present while four 6to4 are present ? I searched the internet for answers to the above queries, but I am unable to find clear answers.

  • File/folder permissions and groups on Linux with Apache

    - by phobia
    I'm trying to learn about permissions on linux webserver with apache. Some clues to the system: The server I have to play around with is Fedora based. Apache runs as apache:apache. To allow for e.g. php to write to a file the file needs to be chmod 777. 755 is not sufficiant. What I'm wondering is basically how set up permissions like they should be on e.g. a "shared web host". My main problem is that if I set a permission so that one user cannot access anothers home folder, then apache can't read from the public_html folder either. To keep the users out I need to set chmod 700. But to let apache to read I need to have at least execute on world, so a 701 basically works, but won't let some users in. So I'm really stuck on what to do. Have been concidering adding the apache user to the frous grours below to avoid having to add the world execute flag, but is that a bad thing? Should it be the other way around, the users in the groups below should also be in the apache group? I was aiming at having 4 groups: 1. webapp same as dev_int, but is the only one that can go inside the webapp/live folder to e.g. do an update from the repo. 2. dev_int can read,write and execute everything in the "web root", including the two below, but nothing outside of the web root 3. dev_ext can read write and execute in all client folders, but cannot access anything outside of the webapp root 4. clientsBasic ftp accounts. Has a home folder with a public_html, but cannot access any other home folders An example of folder structure: webroot    no users in the aforementioned groups can go outside of here some_project    :dev_int only webapp live    :webapp only staging    :dev_int and :dev_ext clients    :dev_int and :dev_ext client_1    :dev_int, :dev_ext and client1:clients public_html dev developer_1    developer_1:dev_int OR :dev_ext public_html

  • Setting up a home server - what to use? (ZFS vs btrfs, BSD vs Linux, misc other requirements)

    - by monch1962
    I need to get all our home content off individual machines and onto a central server. What I'd like to have is the metaphorical "server under the stairs". Stuff we need: expandable storage. I want to be able to add extra disc as we go along, with minimal maintenance required. Currently we've got about 3Tb of files we need to host, and that's likely to grow by another Tb every 6-12 months based on recent history. I need to be able to add additional disc with minimal pain needs to store all the media (i.e. photos, video, music) we have, and run services to serve the various devices we have in the house to playback (e.g. DAAP so we can play stuff through iTunes, ccxstream so we can play stuff over XBMC). DAAP and ccxstream are needed now, but we also need to support new standards as they emerge (so a closed-box solution isn't going to work) RAID 5, or something broadly equivalent (e.g. RAID-Z) BitTorrent client ssh, NFS, Samba access snapshot capability (as in ZFS), so we can snapshot individual file systems regularly and rollback when my kids delete their school assignments the day before they're due... ability to recover quickly from power outages (it's not unusual for us to have power outages that last longer than our UPS' batteries) FOSS software a modern distributed version control system running on the box, such as Mercurial Stuff I'd like to have on the server, but can live without: PVR capability, so I could record TV to the box Web server. We currently run a small Web server on a very old box, and I'd ideally like to turn the old box off and move the content to the new server just to save some electricity Nagios + mrtg I've been looking at using a EEE Box as the server, primarily because I can get them cheap and they don't consume much power. The choice of OS and file system is more difficult, from what I've found: I've got most experience with various Linux distros, but am happy to use another Unix FreeBSD and OpenSolaris seem to be the best choices for hosting ZFS OpenSolaris' hardware support is nowhere near as good as e.g. Ubuntu btrfs, while looking very good, doesn't seem ready for prime-time yet ZFS doesn't let you (easily?) add new discs to a RAID5 or RAID-Z reading around, it seems that ZFS is a bit short of tools for recovering lost data At the moment, I'm leaning towards running FreeNAS+ZFS, but I'm concerned about the requirement to be able to add new disc on a fairly regular basis to an existing RAID-Z. Can anyone provide some recommendations, or share experiences? Thanks in advance

  • Disk IO causing high load on Xen/CentOS guest

    I'm having serious issues with a xen based server, this is on the guest partition. It's a paravirtualized CentOS 5.5. The following numbers are taken from top while copying a large file over the network. If i copy the file another time the speed decreases in relation to load average.

  • Avoid read-write access to bad sectors on HDD to continue working on the HDD

    - by goldenmean
    I have a HP Pavilion dv6446 notebook. It had Windows Vista Home premium. After 4.5+ years of usage, just recently it started malfunctioning. While working fine, its screen goes white or sometimes some thin black lines horizontally. Laptop freezes. Hard reboot works. Again it works for some 2 hrs or so, same error. To diagnose I did run the Memory and Hard disk check which is present in the Bios Setup. Memory test passed. Hard disk test returned an error saying something like - "Replace the hard disk". Bad.. Some sectors or platters have gone bad on the disk. (I confirmed this later by further tests mentioned below) Then I tried installing a Ubuntu 11.10. It listed 3 partitions /dev/sda1, sda2, sda2. It again gave error and could not install grub loader on /dev/sda1. Bad sectors. Then redid the Ubuntu installation, this time asked to to install the Ubuntu on /dev/sda3. and kept /dev/sda1 for /home. Installed fine, and works fine as well. Due to unavailability of WiFi/ Ethernet driver for that adapters under Ubuntu( at least I could not configure them and get the networking working at all), I decided to go back to reinstall windows Vista. It did install fine. I did not have to format one data partition which has my data. I just formatted one partition which installed Windows So in effect HDD has not undergone a full format here. Worked ok for 1 day. But same white screen and freeze happened. Looks like while it is in use, it accesses the bad sectors for storing some data and that's when it bombs. I am inclined to think HDD has not failed fully or crashed but has developed bad sectors. Else if it was a HDD crash, it would have refused to boot at all let alone install on it. Questions: Is there any HDD test check under windows or any such tools windows/linux based ewhere which can identify the bad sectors of the HDD and 'lock/isolate' them from further read-write access of any kind. If not what are my options, if any to salvage this laptop HDD without replacing it. EDIT: Would the Disk Error checking tool under windows help in any way?

  • PHP app breaks on Nginx, but works on Apache

    - by rizon1990
    I want to migrate a PHP application from Apache to Nginx. The problem is that the App breaks, because the routing doesn't work anymore and I'm not exactly sure how to fix it. The PHP application includes some .htaccess files and I tried to convert those to Nginx. The first one is in the document root: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ public/ [L] RewriteRule (.*) public/$1 [L] </IfModule> The second one is in /public/ <IfModule mod_rewrite.c RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d # Rewrite all other URLs to index.php/URL RewriteRule ^(.*)$ index.php?url=$1 [PT,L] </IfModule> <IfModule !mod_rewrite.c> ErrorDocument 404 index.php </IfModule> The third and last one is: deny from all My nginx version of it looks like the following: #user nobody; worker_processes 1; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; #tcp_nopush on; keepalive_timeout 65; gzip on; server { listen 8080; server_name localhost; root /Library/WebServer/Documents/admin; location / { index index.php; rewrite ^/$ /public/ break; rewrite ^(.*)$ /public/$1 break; } location /public { if (!-e $request_filename){ rewrite ^(.*)$ /index.php?url=$1 break; } } location /library { deny all; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ \.php$ { root /Library/WebServer/Documents/admin; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } } The problem I face is that something that the routing is broken and just returns a 404 page instead. Hopefully someone has an idea and know how to fix it ;) Thanks EDIT I got it working with this config location /library { deny all; } location ~* ^.+.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js)$ { access_log off; rewrite ^(.*)$ /public/$1 break; } location / { rewrite ^/(.+)$ /index.php?url=$1 last; } I'm sure there are better solutions and I'm open for suggestions.

  • grep simply fails when used on a few files

    - by Reid
    I've been trying for about the past 30 minutes to get this to work properly. grep is not exactly the most difficult thing to use, so I'm somewhat baffled as to why this won't work. The files I'm trying to use grep on are simple XHTML log files. Their names are in the format [email protected], though I don't think that should matter, and inside is simple XHTML. I copied one such log file to be testfile so you can see the output of some commands and why it's baffling to me: [~/.chatlogs_windows/dec] > whoami reid [~/.chatlogs_windows/dec] > type grep grep is /bin/grep [~/.chatlogs_windows/dec] > uname -a Linux reid-pc 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:32:27 UTC 2010 x86_64 GNU/Linux [~/.chatlogs_windows/dec] > head -1 /etc/issue Linux Mint 10 Julia [~/.chatlogs_windows/dec] > ls -Alh | grep testfile -rw-r--r-- 1 reid reid 63K 2011-01-10 12:45 testfile [~/.chatlogs_windows/dec] > tail -3 testfile </body> </html> [~/.chatlogs_windows/dec] > file testfile testfile: XML document text [~/.chatlogs_windows/dec] > grep html testfile [~/.chatlogs_windows/dec] > grep body testfile [~/.chatlogs_windows/dec] > grep "</html>" testfile [~/.chatlogs_windows/dec] > grep "</body>" testfile [~/.chatlogs_windows/dec] > cat testfile | grep html [~/.chatlogs_windows/dec] > cat testfile | wc -l 231 [~/.chatlogs_windows/dec] > cat testfile | tail -3 </body> </html> [~/.chatlogs_windows/dec] > chmod a+rw testfile && ls -Alh | grep testfile -rw-rw-rw- 1 reid reid 63K 2011-01-10 12:45 testfile [~/.chatlogs_windows/dec] > grep html testfile That's what I'm attempting to do. I want to just use grep -ri query . in ~/.chatlogs_windows, which normally works perfectly for me... but for some reason, it completely fails at going through these files. If it matters, I copied these files off of my Windows 7 partition. But I chown'd them and gave myself all the appropriate permissions, and other programs (like cat) seem to read them just fine. I also copied testfile to testfile_unix and converted the line endings and tried that, but it didn't work either. I'm using zsh, but I tried it on bash and that failed too. Also, grep works normally: I tried it out on my documents folder and it worked flawlessly. If you need any more information, just let me know. I tried googling around, but I found no reason for grep to simply not work. Thanks in advance.

  • Windows 8 with LiveID login authenticates as Guest to remote SQl Server

    - by Tim Long
    I have a network where several users are using Office Accounting 2009 in multi-user client/server mode. OA is built on SQL Server. One PC acts as the 'server' and has the SQl Server instance, the others have only the application installed and no SQL instance, all of the apps connect remotely to the SQL instance on the 'server'. I'm using the term 'server' loosely here, it is just a normal workstation that happens to be designated as the server and runs the SQL instance. There is no NT domain, all user accounts are local accounts. The way that OA works in multi-user mode is that each user is required to have a local account with the same username and password on both the client and 'server' PCs. This has been working well, no along comes Windows 8. I use my 'Microsoft Account' aka LiveID to log into Windows 8. Office Accounting runs fine and attempts to connect to the database, but fails, 'you do not have permission to perform this operation'. In the SQL logs, I get this error: 2012-10-28 17:54:01.32 Logon Error: 18456, Severity: 14, State: 11. 2012-10-28 17:54:01.32 Logon Login failed for user 'SERVER\Guest'. Reason: Token-based server access validation failed with an infrastructure SERVER is the hostname of the server. So it seems to be authenticating as 'Guest'?? To verify this, I enabled the Guest account on the 'server' PC and then added Guest as an allowed user within Office Accounting (this simply creates the user in SQL and gives it an appropriate database role). Sure enough, My Windows 8 PC was then able to connect to the database when using Office Accounting. Clearly, having users authenticate as 'Guest' stinks from a security and auditing standpoint. So what I need are some ideas for how to work around this. I've tried switching the Windows 8 PC to a 'local account' and that works too, but requires giving up significant functionality on the Windows 8 PC. What I really need is a way to force the Windows 8 PC to use a specific set of credentials when connecting to the remote SQL instance. Office Accounting takes the logged in username, which is my LiveID and doesn't correspond to any Windows user name. Anyone solved this issue?
